Abstract We present a simple and practical scheme for performing ab initio calculation of electron chemical potential on the basis of theoretical model introduced by one of the authors. This model allows the use of the well known and measurable mechanical parameters of metals (in article elastic bulk modulus) to modify the function of the density of states and then to calculate the electron chemical potential. Numerical calculations were made for alkali metals and for comparison for two other metals with well-defined valence number: cadmium and lead. In the last section we analyzed the dependence of the chemical potential on temperature. We hope this article, linking clearly the micro and macroscopic quantities, will be useful for a deeper understanding of many phenomena occurring on the metal surface as well as on the joints of any two metals.
